The Republican Governors Association is orchestrating the call and said Tuesday that it is expecting 30,000 people to participate.

Both governors will speak for a few minutes at the beginning of the call before opening up the forum to up to an hour of listener-submitted questions.

“I'm not a technology guy, and so it's been explained to me,” Sanford said of the format. “It'll be somewhat awkward.”

Though Sanford set the bar low for the Thursday night call, he said he is hoping to “learn more of what's happening at a grass-roots level so that we can take those ideas and try and plug them into places in our respective states.”

“I suspect there'll be Tea Party 2.0 and 3.0 and 4.0 and 5.0, and go down the list, because what I saw at the original Tea Party was a level of political energy that I've not seen in the last 15 years that I've been involved in the political process,” he said.

“Whether it's in this 2.0 version that we're going to have or some other version, there's going to be a movement that's created.”
